Anyone know if new bases will be added if the Klingons get more sectors available to them?

Will they be Drozana-like stations? Or places exclusive to the KDF?

Also, will the KDF be able to access the current exploration zones (IE: Rolor, B'tran, Khazan, et al)? And if so, what happens to the Exploration Zones surrounding Omega Leonis?
Will we eventually see the Klingon Empire expanding southwards as well?

I don't think they have mentioned adding any more starbases. I'd be surprised if that was part of the Season Four launch release.

I don't think they've addressed the Federation's exploration clusters either. I have no idea whether we will have access to them. Even if we do, I suspect we won't be able to take advantage of missions in there.

From the sounds of it, Klingons may have limited access to DS9 for an upcoming Featured Series, but it doesn't sound like we [Klingons] will be getting access beyond that. What level of access Klingons get is still being discussed.

I dont see how they could make that work. After all the two sides are at war. The only reason we share Drozana is because neither side runs it. DS9 is clearly in the hands of the federation.

I'd love to see 1 or 2 new ones spread out through the galaxy though. I dont know how they'd make that work either, since you'd have a kdf base or station in someone else's territory

They could probably put one in Pi Canis if they wanted to. Maybe put something near Romulan territory and have it as a staging area for the Klingon fleet. I agree that it would be difficult to make other Klingon bases though. Many of these sectors were designed for Federation gameplay.

An alternative I proposed when the Romulan Weekly series launched along with an additional sector open for KDF players was to place a carrier as a new "Solar System" there.
Carriers are really large flagships intended for operations far away from Klingon space and have docking facilites for other ships so they can be serviced and resupplied.

So why not do exactly that?
Put an NPC carrier that is escorted by a bunch of NPC ships into a new section in the newly-opened sector blocks that is available to KDF players only.
Have the smaller ships patrol the area around the carrier where you can dock.
Use the existing interior for Klingon ships and place several NPC vendors and possibly Quest Givers throughout the interior.

We (the KDF) should seize and claim Empok Nor for our own, we will rechristen it yoDjuH'a' vo' 'Iw. It's very name will freeze the hearts of our enemies.

It would only require the alteration of one mission Fed-side (the Long Night, make it some other Cardassian Station left over from the Dominion War set in Zeta Adndromedae), the art assets are already in the game, and the upcoming revamp of DS9 for the next FE could benefit us as well.

We should also seize a former Reman base ala Frozen, a Romulan D'Deridex Cruiser buried in an asteroid, with fully functioning cloaking device, would make an excellent advanced operations base in either the Psi Velorum, or Iota Pavonis Sector blocks, and again, the art assets are already there.

Throw in the long-promised KDF version of Diplomacy, and we could even get our own version of the Diplomatic Transwarp accolades (to Ganalda, Empok Nor, & ~buried D'Deridex~ respectively).

And, because we'll be gaining access to all sectors but Sirius, we could even mount a campaign for our own Advanced Heavy Battle Cruiser Retrofit with Sector-Transwarp.

All this would be possible with relatively little investment from Cryptic, I think, at least, little investment compared to creating two brand new KDF Stations, with their own assets, layouts, etc..
